PR Summary

Fixed critical ElevenLabs TTS functionality in deployed environments by implementing persistent audio storage. Previously unusable blob URLs are now replaced with stable storage URLs.

• Modified apps/sim/app/api/proxy/tts/route.ts to store audio files in S3/Azure instead of returning raw blobs
• Updated apps/sim/tools/elevenlabs/tts.ts to handle JSON responses containing stored audio URLs
• Added proper error handling and logging for storage operations
• Ensured audio URLs remain accessible across different contexts and browser sessions
